- the gas from the inflator 22 is introduced into the airbag 30 through the gas inlet 32h.
- the gas is introduced into the airbag 30 through the rectifying member 40 from the gas inlet 32h.
- the airbag 30 first tries to deploy in a planar shape in the vehicle front-rear direction.
- the airbag 30 in the substantially planar folding form is folded in the upper portion from the vicinity of the opening 41 h in the lower portion thereof. In a portion (see WA portion in FIG.
- the small air chamber is formed while the lower end vicinity position A is directed toward the rear side of the vehicle, so that expansion is attempted.
- the lower end vicinity position A can be inflated and deployed more reliably with the vehicle rear side directed.
- the portion of the upper portion of the airbag 30 that has been folded into the airbag 30 and pressed into the airbag 30 is pressed into an overlapped state by the internal pressure of the air, and rapid inflating and deployment is suppressed.
- the portion of the upper portion of the airbag 30 that is folded in the valley and folded into the airbag 30 is deployed later than the portion that expands while forming a small air chamber in the portion WA.
- the small air chamber by the portion WA is further expanded and deployed as shown in FIG. 11, and the valley portion of the upper portion of the airbag 30 is folded.
- the portion folded into the airbag 30 also tends to inflate and deploy.
- the small air chamber formation part by said part WA becomes a certain size, as shown in FIG. 12, it will rotate below the attachment part of the airbag 30 downward. This rotational movement is performed by any one or a combination of actions described below. In other words, the distance between the position A near the lower end of the airbag 30 and the fixing position of the airbag 30 is shorter in the lower part than in the upper part of the airbag 30.
- the small air chamber forming portion by the portion WA is pulled in the vehicle front-rear direction, and the upper portion is the vehicle front-rear direction. It is in a relaxed state. For this reason, the small air chamber forming portion by the portion WA is pulled downward, and can act as a force for rotating the small air chamber forming portion by the portion WA downward. Further, the internal pressure acting on the small air chamber forming portion by the portion WA by introducing the gas mainly acts as a direction (relative force for inflating) to release the slackness of the airbag 30 in the upper portion of the small air chamber forming portion by the portion WA.
- the lower portion that has already been inflated and deployed can act mainly as a force for pushing downward, that is, as a force for rotating the small air chamber forming portion by the portion WA downward.
- the portion of the upper portion of the airbag 30 that has been folded into the valley and is folded into the airbag 30 is inflated and deployed, it comes into contact with the inner surface of the front window 12, so It can act as a force that pushes the small air chamber forming portion by the WA downward so as to be separated from the front window 12, that is, a force that rotates downward.
- the small air chamber forming portion by the portion WA rotates downward.
- the lower end vicinity position A gradually moves downward while inflating and deploying the upper vehicle front position B vicinity as shown in FIG.
- the airbag 30 is inflated and deployed until the position A near the lower end moves to the lower end.
- the passenger seat occupant D when the passenger seat occupant is in the non-regular seating state and close to the instrument panel 10, the passenger seat occupant D is in a relatively early stage after the airbag 30 is inflated and deployed, as shown in FIG. Contact the bag 30.
- the small air chamber forming portion by the portion WA is in a state where the internal pressure is increased to some extent. Therefore, the impact of the passenger seat occupant D can be received. Even in this state, it is preferable to form a vent hole in the small air chamber forming portion by the portion WA in order to perform degassing at the time of receiving an impact.
- the airbag 30 tries to rotate the small air chamber forming portion by the portion WA downward. While expanding. At this time, as shown in FIG. 17, the position A in the vicinity of the lower end of the airbag 30 is in contact with the head of the passenger occupant D, so that the portion WA is formed below the small air chamber forming portion. Movement is suppressed. As a result, as shown in FIG. 18, the airbag 30 is inflated mainly above the passenger seat occupant D. For this reason, after the contact between the airbag 30 and the passenger seat occupant D, the impact on the passenger seat occupant D acting on the passenger seat occupant D is mitigated by further inflation and deployment of the airbag 30.
- the airbag 30 when the gas from the inflator 22 is introduced into the airbag 30, the airbag 30 first tries to expand into a substantially planar form.
- the airbag 30 In this substantially planar form, the airbag 30 is folded so that the upper portion has a surplus length and the surplus length portion is folded into the airbag 30 toward the rear of the vehicle.
- it In order to form a small air chamber mainly in the lower part, it tries to expand and deploy in a bag shape.
- the airbag 30 is further inflated and deployed by rotating the small air chamber forming portion downward while inflating the upper portion.
- the occupant can be received in the small air chamber forming part or the part further expanded from the state, and the occupant can be received in the inflated part. It can be received more reliably.
- the airbag 30 is inflated and deployed while rotating the small air chamber downward, so that the protruding behavior toward the occupant side is suppressed. The Accordingly, the occupant can be more reliably received at the inflated portion with a relatively simple configuration without performing additional stitching of the tether, and the occupant side of the airbag 30 after being inflated to some extent. Protruding behavior can be suppressed.
- the gas introduced from the gas introduction port 32h is guided to the rear side in the airbag 30 by the rectifying member 40, the inflation and deployment behavior of the airbag 30 is stabilized, and the position A near the lower end of the airbag 30 is set. It can be inflated and deployed so as to form a small air chamber mainly in the lower portion while projecting more reliably toward the occupant side.
- the airbag 30 is folded so that the position A near the lower end in the inflated and deployed form is located at the end on the vehicle rear side. It can be inflated and deployed so as to form a small air chamber mainly in the lower part while projecting to the side. Thereafter, the airbag 30 as a whole can be inflated and deployed while rotating the small air chamber forming portion downward. For this reason, the airbag 30 can be rapidly inflated and deployed while suppressing the protruding behavior of the airbag 30 toward the passenger after the airbag 30 has been inflated and deployed to some extent.
- the lower end vicinity position A may be set to any position in the region facing downward in the inflated and deployed form of the airbag 30, and preferably the position of the lowermost end part in the inflated and deployed form of the airbag 30 Is set to
- the airbag 30 is folded in a bellows shape so that the vehicle rear side end portion (here, the position A in the vicinity of the lower end portion) in the substantially planar folding form is disposed at the uppermost portion,
- the airbag 30 is easily inflated and deployed smoothly in the vehicle front-rear direction in the initial state of inflation and deployment. Thereby, it is easy to inflate and deploy the lower part of the airbag 30 stably and quickly so as to form a small air chamber.

- column of FIG. 19 has shown the expansion
- the row (c) of FIG. 19 shows a comparative example in which the same airbag 130 is folded into a storage configuration after being folded into a substantially flat shape while having the same size in the vehicle front-rear direction at the upper portion and the lower portion. The unfolding behavior when folded is shown.
- the dummy doll D in the non-regular seating state is installed, as shown at time t1 in the row (b) of FIG. 19, the dummy doll D is in a state where the air bag 30 forms a small air chamber. Then, as shown in time t2 to t6, the head of the dummy doll D is immersed in the small air chamber forming portion of the airbag 30, and the remaining portion of the airbag 30 is mainly used. It has been confirmed that the dummy doll D expands and expands above the head.
- the airbag 130 remains in a state where the internal pressure remains small due to wrinkles as a whole. It was confirmed that, at time t3, it greatly protruded toward the occupant side, and thereafter the lower portion (the chest area of the passenger occupant) expanded and expanded.
